Abstract (en)
A three-dimensional powder bed fusion additive manufacturing (PBF-AM) apparatus (1) includes a movement mechanism (5), a stage (4), a plurality of support columns (11), a base plate (10), and a shielding member (12). The base plate (10) is supported by the plurality of support columns (11), and a powder material (M1) for forming a product (P1) is laminated on the base plate (10). The shielding member (12) surrounds the plurality of support columns (11) between the stage (4) and the base plate (10).
